Additional markings shall be permitted based upon the specific system configuration. For PV system disconnecting means where the line and load terminals may be energized in the open position, the device shall be marked with the following words or equivalent. NEC 690.13(F) Type of Disconnect. A dc PV system disconnecting means shall be marked for use in PV systems or be suitable for backfeed operation. NEC 690.15(C) An isolating device shall be rated to open the maximum circuit current under load or be marked “Do Not Disconnect Under Load” or “Not for Current Interrupting.” NEC 690.31(B)(1) PV system circuit conductors shall be identified at all accessible points of termination, connection and splices. The means of identification shall be permitted by separate color coding, marking tape, tagging or other approved means. NEC 690.31(G)(1) Where circuits are embedded in build up, laminate or membrane roofing materials not covered by PV modules and associated equipment, the location of the circuits shall be clearly marked. NEC 690.31(G)(4) PV dc system circuit labels shall appear on every section of the wiring system that is separated by enclosures, walls, partitions, ceilings, or floors. Spacing between labels or markings, or between a label and a marking, shall not be more than 3 m (10 ft). Labels required in this section shall be suitable for the environment where they are installed. NEC 690.31(I) Solidly-grounded bipolar PV systems shall be clearly marked with a permanent, legible warning notice indicating that the disconnection of the grounded conductor(s) may result in overvoltage on the equipment. NEC 690.33(E)(2) Interruption of Circuit. Connectors shall be a type that requires the use of a tool to open and marked “Do Not Disconnect Under Load” or “Not for Current Interrupting.” NEC 690.52 Alternating-current modules shall be marked with identification of terminals or leads and with identification of the following ratings. NEC 690.53A permanent label for the dc PV power source indicating items (1) through (3) shall be provided by the installer at dc PV system disconnecting means and at each dc equipment disconnecting means required by 690.15. Where a disconnecting means has more than one dc PV power source, the values in 690.53 (1) through (3) shall be specified for each source. NEC 690.54 All interactive system(s) points of interconnection with other sources shall be marked as an accessible location at the disconnecting means as a power source and with the rated ac output current and the nominal operating ac voltage. NEC 690.55 The PV system output circuit conductors shall be marked to indicate polarity where connected to energy storage systems. NEC 690.56(B)Plaques or directories shall be installed in accordance with 705.10. NEC 690.56(C)(3) A rapid shutdown switch shall have a label located on or no more than 1 meter (3 ft) from the switch that includes the following wording. NEC 690.56(C)(1)(a-b) The type of PV system shall be labeled as described in a) or b): NEC 690.59 PV systems connected to other sources shall be installed in accordance with Parts I and II of Article 705.
